SN75437ANEE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN75437ANEE4 is a quadruple peripheral driver manufactured by Texas Instruments, designed for high current, voltage, and load power applications. It features four inverting open-collector outputs with a common-enable input. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an output current up to 0.5 A. It is characterized for operation over a free-air temperature range of 0°C to 70°C and is packaged in a thermally enhanced plastic DIP (NE) with 16 pins.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features saturating outputs with low on-state resistance and high-voltage capabilities reaching 70 V minimum.
• Includes output-clamp diodes specifically designed for transient suppression.
• Ensures no power-up or power-down output glitches during operation.
• Provides high-impedance inputs compatible with both CMOS and TTL logic levels.

Buffers, Drivers, Receivers, Transceivers Applications

• Driving relays
• Driving lamps
• Driving solenoids
• Driving motors
• Driving LEDs

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to lead-free material specifications as defined in the manufacturer's packaging addendum. Confirm that the PDIP package dimensions align with the target PCB footprint requirements. Ensure the thermal dissipation characteristics are adequate for the intended operating environment without exceeding continuous total power dissipation limits.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when the application requires driving high-power loads such as inductive devices or lamps directly from logic circuits. The common-enable feature allows simultaneous control of all four channels. Consider the thermal performance of the plastic DIP package if multiple channels conduct rated current simultaneously to maintain safe operating temperatures.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75437A family of quadruple peripheral drivers. It is distinct from standard logic buffers due to its ability to handle high voltages and currents. The device is suitable for systems needing robust interface capabilities between low-power control logic and high-power peripheral equipment.
